In this embodiment, can the background image that switches above-mentioned that kind on the medium print earlier with background image after prints and prints (below, be called and switch printing) so that 41 nozzle uses as following explanation.
< switching pattern 1 >
Fig. 5 A is the 1st key diagram of switching pattern 1, and Fig. 5 B is the 2nd key diagram of switching pattern 1.Originally, the key diagram of the switching pattern that Fig. 5 A and Fig. 5 B are represented was a figure, but was divided into two figure according to situation on paper.Fig. 5 A partly combines at the thick line of represented respectively Reference numeral A with Fig. 5 B.Through with reference to two figure, accomplish all figure of switching pattern 1.
In the drawings, the epicranium of injector spacing D illustrates.In addition, simple for what explain in the accompanying drawings, the nozzle quantity that belongs to 1 nozzle rows is reduced to 10 and describes.In addition, each is sprayed concentrated be expressed as " the color nozzle row Co " of nozzle rows of 4 chromatic inks (YMCK).In addition, in the accompanying drawings, the throughput direction of medium is illustrated, and is illustrated with respect to the relative conveying capacity of the medium of head.In addition, the moving direction (moving direction during injection) of the head when spraying ink is towards the direction in left side from the right side of paper.
In addition, each PASS is illustrated, and the nozzle numbering that in each PASS, is used encloses with circle, triangle and quadrangle.The meaning of the symbol of writing is described below.
Circle: the nozzle that forms coloured image
Triangle: the nozzle that forms background image
Quadrangle: the nozzle (toning is described in the back) that can be used in toning
In addition, when not mixing colours, ink is not from there being the nozzle ejection of tetragonal symbol by mark.
Condition according to such prints, in white zone earlier (since as a setting the white of look than the first formation of coloured image, so call like this.Being equivalent to background image prints earlier) printing in, use white nozzle rows (nozzle # 6～#10) form background image, (the formation coloured image of nozzle # 1～#5) that uses the color nozzle in downstream to be listed as of upstream side on one side on one side.
In addition, in white rear region (because the white of look forms coloured image after as a setting, so call like this.Be equivalent to print behind the background image) printing in, (nozzle # 6～#10) form coloured image uses white nozzle rows (the formation background image of #1～#5) in downstream on one side Yi Bian use the color nozzle row of upstream side.
Like this, through carrying out the printing as switching pattern 1 is represented, can switch to the printing of white rear region from the white printing in zone earlier.
< about toning >
Yet if only use white ink to print background image, the color of color itself of printing the white ink of background image becomes the color of background image.But even if be called as the ink of white ink equally, because of the difference of the material of ink etc., the tone of white is some difference also.Therefore, there is situation about being printed as because of the white ink that uses is different with the background image of the desirable color various colors of user.In addition, different according to printing thing, also not hope it is simple white sometimes, but have the background image of a little colour.In addition, under the situation of the medium that uses white, on the medium of white, also can be because of the difference of the kind of medium, and make some difference of tone of white.Therefore, when on the medium of white, printing background image, if the white of background image and medium is white different, then background image can be very showy.
Therefore, suitably together use a spot of color inks (YMCK), also can print the background image (background image of adjusted white) of desirable white with white ink.For example, in the embodiment shown in Fig. 5 A and Fig. 5 B, as stated, from enclose a spot of ink of nozzle ejection of the numbering of coming by quadrangle.Like this, white ink is had under the situation of a little color, can in the ink of eliminating this color, print background image, therefore can make background image approach netrual colour because of utilizing white ink and color inks to print background image.
< switching pattern 2 >
In above-mentioned switching pattern 1, carry out continuously from white zone earlier to the passing of white rear region.Yet changing method is not limited thereto.For example, as follows, after the zone individual region is set earlier white, also white rear region can be set afterwards.At this, individual region is meant, only forms the zone of coloured image or background image.
Fig. 6 A is the 1st key diagram of switching pattern 2, and Fig. 6 B is the 2nd key diagram of switching pattern 2.These were a figure originally, but were divided into two figure in this situation according to paper.Fig. 6 A partly combines at the thick line of the Reference numeral B that illustrates respectively with Fig. 6 B.Through such reference two figure, accomplish all figure of switching pattern 2 (its 1).In addition, all figure of switching pattern 2 (its 1) represent from white zone earlier to the situation of individual region switching.
In addition, Fig. 7 A is the 3rd key diagram of switching pattern 2, and Fig. 7 B is the 4th key diagram of switching pattern 2.These were a figure originally, but were divided into two figure in this situation according to paper.Fig. 7 A partly combines at the thick line of the reference number C that illustrates respectively with Fig. 7 B.Through such reference two figure, accomplish all figure of switching pattern 2 (its 2).In addition, all figure of switching pattern 2 (its 2) represent from the situation of individual region to white rear region switching.
Here, simple for what explain, the nozzle quantity that belongs to 1 nozzle rows is kept to 10 and describes.In addition, each PASS is illustrated, and in the employed nozzle numbering of each PASS, encloses with circle, triangle and quadrangle.The meaning of each symbol is described below.
Circle: the nozzle that forms coloured image in white regional and white earlier rear region
Triangle: the nozzle that can form background image
Quadrangle: the nozzle (still, can in white zone earlier and white rear region, spray the color inks that is used to mix colours) that can form coloured image in individual region
So, can be in individual region printing color image or only print background image only, even and from white zone earlier to and white rear region such individual region is set, also can suitably switch to white rear region from white zone earlier.
